Types of Drip Irrigation System Filters

In the farmland irrigation system, filtration devices are indispensable. Impurities in water are mainly divided into physical impurities, chemical impurities, and biological organic impurities. In practical applications in the field, especially for large areas, it is extremely necessary. Many small-scale drip irrigation systems, covering only a few acres, often forgo the installation of filtration devices. Many farmers believe that the drip irrigation tape, which is replaced annually, is disposable and won't clog. However, long-term use can significantly affect the main pipes.

Sand and Gravel Filter

Sand and gravel filters are generally used in large-scale farmland drip irrigation systems that utilize surface water for irrigation. Typically, these systems are composed of two or more filter tanks connected in parallel through a pipeline at the outlet, forming a filtration station. These filters can remove organic impurities, including algae, moss, some bacteria, and other organisms. For irrigation using lake water, sand and gravel filters are the best choice. They are highly effective in large areas.

Centrifugal Filter

The centrifugal filter uses the principle of centrifugal force to make the water rotate and separate the sand from the water. As long as the selection is appropriate and the system flow rate is constant, the sand and gravel separator works very effectively. It is mainly used in irrigation water with a high sand content.

Mesh Filter

Mesh filters are more effective for treating water with inorganic impurities, such as silt and sand. They are generally ineffective for water with high organic impurity content. Unlike sand and gravel filters, mesh filters cannot store large amounts of organic impurities and are generally used as secondary filters.

Disc Filter

The disc filter is a type of filter that lies between sand and gravel filters and mesh filters. It consists of multiple thin, circular discs stacked and locked together to form a cylindrical filter element. Water passes through the gaps between the discs, and impurities are trapped in the filter grooves.

Y-Filter

For water containing sand or other debris, these impurities can damage valves, pump impellers, and other components of the drip irrigation system. Various Y-filters are commonly used to handle these impurities. They are generally installed downstream in the filtration system as secondary filters or at the head of field branch pipes to prevent capillary clogging.
